IPC: G02B7/36
Filed: 1980-07-10
Abstract: PURPOSE:To decide focusing state by utilizing a peak of an output, while the disposition of photodetector-arrays are made to be less significant, by disposing one of the photodetector-arrays vertically to an optical axis and the other of arrays obliquely, at a position corresponding to an image forming surface. CONSTITUTION:At a position of an image forming surface P of a lens L, the 1st photodetector-array SA is disposed vertically to an optical axis, the 2nd photodetector-array SB is disposed obliquely to this axis, and these arrays output image signals VA, VB respectively. Despite the positions of the detectors in each array, if there is a relation VA'>=VB' between contrast distributions VA', VB' of the image signals VA, VB a focusing state is decided. And, if VA'<VB' in a domain of detectors in rear of position (m) of the detector corresponding to the position P of the image forming surface, a state is decided as a rear focus; if VA'<VB' in a domain of front detectors, a state is decided as a front focus.

Title: Nuclear fusion utilizing heavy fermion effect in solid
Inventor: MIZUKAI TOSHIHARU
IPC: G21B3/00
Filed: 1989-04-13
Abstract: PURPOSE:To enable a realization of a nuclear fusion in a small apparatus by absorbing a deuterium into a heavy fermion compound or a composite body of a heavy fermion compound and a hydrogen storage material. CONSTITUTION:A fusion reaction is made to occur by feeding a normal pressure or pressurized deuterium gas 2 to a fusion reaction element 1 containing a heavy fermion compound, and the generated heat is absorbed by a water 3. There are two kinds of the element 1. The first one is an element solely using a compound showing a heavy fermion effect (uranium compounds and the like) out of elements which are considered to be hydrogen storage materials inherently containable a substantial amount of hydrogen such as Pd compounds and U compounds. The second one is a joined body of the heavy fermion compounds and a hydrogen storage material (Ti or V, for instance). In this way, by shielding electrical charges of deutrons, utilizing electrons having a very heavy mass derived from the heavy fermion effect in a solid, a nuclear fusion can be realized in an extremely small apparatus. Also, with this method, an energy can be unlimitedly obtained from a water.

Title: Detection for stratification of liquid in storage tank
Inventor: KONDOU JIYUNICHI
IPC: G01N21/41
Filed: 1981-06-18
Abstract: PURPOSE:To enable a quick and highly accurate detection of stratification in a storage tank by checking a stratified state utilizing refraction of light due to changes in the strtification by providing a projector and a photo detector at the upper and lower part in a storage tank. CONSTITUTION:When a liquid in a tank 1 is not stratified, a light beam from a projector 4 moves stratight through the liquid and mostly reaches a photo detector 6. A large quantity of light is received by the photo detector 6 and a warning lamp 8 is kept from lighting. On the other hand, as the liquid is replenished with a new liquid from a liquid injection tube 2, it is stratified due to a difference in the composition and the temperature between the residual liquid and the replenished liquid and the light beam 5 from the projector 4 is refracted on the interface between the upper layer liquid 11 and the lower layer liquid 12. This is detected with the photo detector 6 because of reducing the quantity of the light  reaching the photo detector 6. The warning lamp 8 is actuated to light. Thus, it  is enabled to find the generating of stratification of the liquid at the foreboding  or initial stage.
